Make sure the VFD of choice will run on single-phase. Some have phase
loss
detection which shuts down the unit if a phase goes down.

Is that a parameter that can be changed through programming?
It's a pretty unusual feature on small (10-20HP?) VFDs. In
20+ years of building and working around industrial
machinery I've never actually run across a small VFD that
wouldn't run on single phase.

I have a 25 HP and a 45 HP VFD for future projects. They are the ones I'm
concerned about. I'll try Don's suggestion if there's a problem.
